824-SPTEdU-seq:空间全转录组测序与新生细胞追踪技术

from 聊聊Sci

这项研究介绍了一项名为 SPTEdU-seq 的创新空间组学技术,旨在克服传统方法在捕捉非编码 RNA 和细胞动态方面的局限。该技术巧妙地结合了 空间全转录组测序 与 EdU 脉冲标记,通过无须光学成像的单分子标签系统,实现了对新生细胞及其微环境的精准追踪。研究人员利用该平台深入剖析了小鼠脑发育、缺血性中风再生以及肿瘤异质性等复杂生物过程,成功重构了细胞重编程的连续轨迹,并识别出促进修复的特定星形胶质细胞亚型。此外,该方法在人类肾癌样本中展现了强大的跨物种适用性,能够检测具有诊断意义的染色体缺失及肿瘤浸润相关的剪接事件。总之,SPTEdU-seq 为探索生命发育、组织再生与癌症演进中的细胞命运决定提供了一个多维且高效的分析框架。References: Niu H, Zhang S, Mao J, et al.
